Currently, `GeneralizePadOpPattern` is grouped under `populatePadOpVectorizationPatterns`. However, as noted in #111349, this transformation "decomposes" rather than "vectorizes" `tensor.pad`. As such, it functions as: * a vectorization _pre-processing_ transformation, not * a vectorization transformation itself. To clarify its purpose, this PR turns `GeneralizePadOpPattern` into a standalone transformation by: * introducing a dedicated `populateDecomposePadPatterns` method, * adding a `apply_patterns.linalg.decompose_pad` Transform Dialect Op, * removing it from `populatePadOpVectorizationPatterns`. In addition, to better reflect its role, it is renamed as "decomposition" rather then "generalization". This is in line with the recent renaming of similar ops, i.e. tensor.pack/tensor.unpack Ops in #116439.
